Well, duh. Yes I did that.
So I looked further and found there was a known issue of having the GUI network dialog write the /etc/network/interfaces file.
The suggested fix started with deleting the GUI network dialog system all together. Then after it was deleted, reboot and write the changes manually. I started to write /etc/network/interfaces file manually then got lost. The example uses eth0. But my eth0 is an on-board network card I don'r use. The network card that goes with the DSL modem is labeled eth1.
Here is another suggested fix that looks better:
I am going to try the above later today. But I would like to know from any Ubuntu users if the above looks correct.
